Evaluation of single-point measurements method for harmonic pollution cost allocation

This paper reports on the reliability of single-point measurements for harmonic pollution cost allocation. Simulated results give the correlation between the cost and four physical electrical quantities that can be measured at the end-user bus: harmonic active power; harmonic apparent power; total harmonic current squared; and nonfundamental apparent power squared. The nonfundamental apparent power squared produced the best correlation, with errors less than 5%.
